Many
but not all ISPs are telephone companies. They provide
services such as Internet transit, domain name registration
and hosting, dial-up access, leased line access and
colocation.
Internet hosting services run servers, provide managed
hosting, and include the Internet connection.Generally,
an ISP charges a monthly access fee to the consumer.
The consumer then has access to the Internet, although
the speed at which this data is transferred varies
widely.
Internet connection speed can generally be divided
into two categories: dialup and broadband. Dialup
connections require the use of a phone line, and usually
have connections of 56Kbs or less. Broadband connections
can be either ISDN, Broadband wireless access, Cable
modem, DSL, Fiber Optics, Satellite or Ethernet. Broadband
is always on (except ISDN that is a circuit switching
technology), and varies in speed between 64Kb and
20+Mb per second. With the increasing popularity of
file sharing and downloading music and the general
demand for faster page loads, higher bandwidth connections
are becoming more popular. |
